Per AP in re: to Wisconsin.
Exit polls showed that half of the voters made their selection in the last week, most in the last few days - and Edwards led among late-breakers. Taking advantage of Wisconsin's open primary rules, one in 10 voters were Republicans and about 30 percent were independents. Those voters broke for Edwards.
It was the strongest turnout of Republican voters in any Democratic contest this year, boosted by city government elections in Milwaukee and a controversial referendum on casino gambling by an Indian tribe.
